Patent JP-H0369420-B2 (JP)
IPC: E04B2/14
Filed: 1984-10-11
Abstract: A sound absorbing block of molded structural material has a sequence of internal cavities that communicate with a region containing the sound to be suppressed through a first elongated slot located in an exterior wall of the block. The internal cavities are defined by interior walls, at least one of which also contains an elongated, sound-communicating slot. Each slot and its associated cavity define an acoustical Helmholtz resonator that dissipates sound energy incident upon the slot with an absorption peak at a natural frequency fn. The value of fn for each resonator is inversely proportional the square root of the volume of the cavity. The internal cavities are arranged to cascade in order of decreasing stiffness beginning at the first slot. In one form, two sequences of cavities in a block use a common final cavity. Also, the exterior slots can be formed in more than one wall to absorb sound produced in multiple regions.

Abstract: Methods and apparatus are set forth for utilizing the restricted token operation on an FDDI network. Two service primitives are defined to facilitate the control of restricted dialog. The first defines what class of token can be captured for the purpose of transmitting asynchronous data. Secondly, a primitive is defined for use at the end of each transmit request to give control over the token type that will be issued at the end of a given transmission. A hardware protocol is defined which provides reliable control over these two parameters, together with methodology for linking frames in a buffer memory during restricted operation. The combination of the hardware protocol and methodology allows restricted dialog to be realized without real-time software interaction.

IPC: G05D16/16

Abstract: An improved vacuum sewerage system for transmitting sewage through an intermittently opened sewage control valve of a transport conduit by means of differential pressure. The vacuum conduit is laid out in a saw-toothed fashion, having a riser, a low point, and a downslope. When no sewage is being transported through the conduit, any residual sewage in the conduit collects in the low point, with minimal intermittent closure of the conduit over time to permit minimal drop in vacuum or subatmospheric pressure throughout the conduit such that there is more than adequate vacuum or subatmospheric pressure available to operate the control valve. When the control valve is opened, the sewage transported through the vacuum conduit forms a generally hollow cylindrical mass, which is propelled toward a vacuum collection tank. The system includes an electric air admission controller ("EAAC"), which automatically opens and closes an air control valve independently of the level of accumulated sewage upstream of the sewage control valve, in order to inject additional air at atmospheric pressure into the vacuum transport lines to apply additional fluid pressure to a mass of sewage therein, and to avoid a waterlogged condition by supplementary transport. A conduit line having more than 13 feet of total lift is thereby possible, provided that the sum of the pressure losses across all the risers equals or exceeds the sum of the minimum subatmospheric pressure condition available at the vacuum collection station minus the pressure head required to operate the control valve.

Abstract: A method of producing a thixotropic material is provided which consists of deforming a fully solidified metal or metal alloy below its temperature of recrystallization by cold or warm working such as extrusion or rolling. The deformed material is then caused to recrystallize by heating and the temperature is either further raised or subsequently raised above the solidus of the material so that the recrystallized structure partially melts to provide discrete particles which spheroidize in the liquid matrix to provide a material which behaves thixotropically. The flow characteristics of the material are such that lower forming loads are required and weaker non-metallic die materials may be used.

Abstract: An infra-red heater (1) for a glass ceramic top cooker comprises a dish containing a base layer of thermal insulating material. A peripheral wall of thermal insulating material extends around the periphery of the base layer and at least one infra-red lamp (3) extends across the base layer. A ballast device (5) is electrically connected in series with the infra-red lamp, for example in the form of a coil of bare resistance wire, and serves to reduce inrush current to the lamp. A thermal cut-out device (7) cuts off the supply of power to the infra-red lamp and to the ballast device (5) if the temperature of the glass ceramic cooking surface becomes excessive. The coil of bare resistance wire preferably has an electrical resistance which is approximately half the electrical resistance of the infra-red lamp at its operating temperature. The use of a ballast device (5) enables the infra-red lamp (3) to be used in conjunction with a cyclic energy regulator (9).
